Title: Method for carbonitriding gear
Inventor: MIURA HIROSHI
IPC: C23C8/32
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the chipping of a gear due to the unnecessary thickening of a layer affected, by nitriding when the surface of the gear is carbonitrided and quenched to carry out surface hardening, by carburizing the surface of the gear before the carbonitriding. CONSTITUTION:A gear 10 to be treated is put in a carburizing furnace 2, a carbon enriched gas is fed and the gear 10 is heated at about 900-930 deg.C to carburize A the surface. A door 7 is opened and the gear 10 is sent to a carbonitriding furnace 3. After the internal pressure of the furnace 2 is made higher than that of the furnace 3, a nitriding gas such as ammonia is fed into the furnace 3 and the surface of the gear 10 is carbonitrided B at about 800-870 deg.C. A door 8 is opened and the gear 10 is sent to a preparation chamber 4, put in a quenching vessel 5 and quenched C. Since high hardness is provided only to a very thin surface layer of the gear 10, the chipping of the gear 10 due to the unnecessary thickening of a hardened layer can be prevented.

Filed: 1989-02-23
Abstract: PURPOSE: To simultaneously support plural wafers by continuously changing an interval between gripping means by gears and racks in plural wafer gripping means, and transferring the wafers between two supports having notch means of a different interval. CONSTITUTION: An interval P between vertically held wafers W is required to be changed for being held by notch means of both supports P, N by being transferred since the notch means are different between one support P and the other support N. Independent carriages 5 to support respective grippers 1 of the wafers W can be translated on a plate 6, and respective carriages 6 are connected to bars acting as racks 9a. These racks 9a are formed so as to cooperate with a gear group 10 having different diameters, and an interval (an interval P of W) between grippers 1 is changed while translating by rotation of the gear group 10. Therefore, gears are rotated according to a movement between the supports P, N of the plate 6 to be adjusted to a notch of both supports P, N.

Title: Dry etching apparatus
Inventor: IDOTA TAKESHI
IPC: H01L21/3065
Filed: 1988-02-26
Abstract: PURPOSE:To strictly control the etching duration by a method wherein a high voltage is impressed instantaneously across high-voltage impression electrodes and an electric discharge is generated under a gas pressure where a plasma is difficult to generate in order to generate the plasma continuously. CONSTITUTION:When an electric discharge is not caused between an electrode 2 and an electrode 3 due to to a low gas pressure inside a reaction container 1 and a plasma is not generated, a high voltage of about 10<4>V is impressed instantaneously across high-voltage impression electrodes 9 and the electric discharge is generated between the electrodes 9. The electric discharge is generated continuously between the electrode 2 and the electrode 3 following the instantaneous electric discharge; the plasma is generated continuously; an object 8 to be processed is etched. Therefore, it is not required to generate the plasma at several Pa and to gradually lower the gas pressure down to a gas pressure by which a prescribed ion incidence energy value can be obtained. By this setup, the etching duration can be controlled strictly.

Title: Production of iron carbide
Inventor: MIYASHITA TORAKATSU
IPC: C21B15/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To efficiently carburize iron into carbide on iron-containing raw material by using the iron-containing raw materials having different reducing ratios as the raw materials, at the time of producing the raw material for iron-making and steelmaking consisting essentially of the iron carbide by reducing and carburizing the iron raw material for iron-making consisting essentially of iron oxides and iron hydroxides. SOLUTION: The mixed raw materials consisting of an iron-containing raw material having high reducing ratio and an iron-containing raw material having low reducing ratio, are used. By this method, the density of H2 O obstructing the carbide formation becomes not uniform in a system, and the iron carbide-formation is promoted from the iron-containing raw material part having low H2 O density and high reducing ratio as the starting point. Further, it is preferable that, after a first reaction operation which executes a part of the reducing reaction, a second reaction operation which executes the remaining reducing reaction and the carburizing reaction is progressed.  By this method, since the gas used for each operation is made to have the most suitable composition, the reduction and the carburization are executed by a faster reacting speed and in a shorter reaction time than those in the single operation using a mixed gas of the reducing gas and the carburizing gas, respectively.

Filed: 1992-03-04
Abstract: PURPOSE:To provide a niobium group Josephson junction with a magnetic tunnel barrier, in which there is no pinhole and no niobium lower oxide film is formed on a junction interface. CONSTITUTION:In a tunnel type Josephson junction, in which a lower electrode 11 and an upper electrode 15 are composed of niobium, a tunnel barrier 13 consisting of a nickel oxide film is held by aluminium 12, 14 having no magnetism. Consequently, the formation of a niobium lower oxide having an adverse effect on quasi-particle tunnel current characteristics on a junction interface by the reduction of a magnetic oxide can be prevented. Since aluminium is made easier to be oxidized than nickel, the thickness of the oxide of aluminium is thicker than that of niobium even when there is a pinhole. Accordingly, tunnel currents are made to flow only through the nickel oxide film.

Abstract: PURPOSE:To improve the controlling capacity of a car, by securing a general steering function which prevents rear wheels from being steered in time of small steering angle operations on a steering wheel, while making these rear wheels steer for opposite phase to front wheels in time of large steering angle operations. CONSTITUTION:In time of steering operations by a steering wheel, a cylindrical cam 13 is rotated by rotation of a pinion shaft to be drawn out of a gearbox of a front-wheel steering mechanism via a linkage shaft 10 and an input shaft 12.
